Nike is hedging all of its bets on fashion’s new obsession with fitness and athleisure — and trust us, this trend still has (toned) legs. The sportswear megabrand has debuted a brand new retail concept at Orange County’s Fashion Island, which brings together its premium women’s running, training and sportswear with an in-store studio for personal fitness or group classes.

“We connect with and inspire millions of women all over the world every day through our Nike+ Training Club and Nike+ Running apps,” said Amy Montagne, VP, GM of Nike Women. “Our women’s business has never been stronger and this new store is the ultimate expression of our commitment to women who run, train and live the look of sport and fitness throughout their day.”

The newly renovated store, which is the very first of its kind in the entire world. Inside, shoppers can find all the latest shoes, workout gear and more from Nike and just outside the gleaming new store, Nike is even offering up demonstrations of the new Flash collection, which is designed with highly reflective materials meant to give runners high visibility even in the dark. Shoppers can slip into one of the new designs and head into a dark box to see just how these jackets react to the tiniest amounts of light.

But back inside the store, there’s also a huge fitness studio. Shoppers can use the space to test out the shoes and apparel that are available, the Nike will be hosting weekly classes in the studio, too. So after you get fitted by an expert bra fitter or you’ve picked out a pair of new kicks, you can take them for a spin before committing to a purchase.

And if the huge shop doesn’t have something you’re looking for (which we’re guessing is pretty unlikely), the new store offers a combination of e-commerce and brick-and-mortar shopping. Purchase anything online from Nike’s website while you’re in the store — they accept Apple’s brand new Apple Pay program, by the way — and you’ll get free shipping. The store even offers pant hemming, so you’ll get the perfect fit for just about anything you need to wear while work out or between your fitness classes.
